To all whom 'it may concern:

.Be it known that I, LOUIS NARowE'rz, a citizen of the United- States, residing at 203 East Kinzie street, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Air-Vl/ashing Apparatus, of which the following is a specification. i

My invention relates to the class of airwashing apparatus for use in cleansing air of dust and dirt reliminary to its use inconnection with lieating and ventilatingsystems by passing the air through water; and my primary objects, generally stated, are rst, to afford a construction by which all of the air drawn into the apparatus shall be subjected to the washing action of the water;-

and second, to reduce. to the minimum the number of baflles required for precipitating the moisture taken up by the air in passing through the water, and thus reduce to the minimum the amount of power required for inducing the desired suction action upon ,the air to be cleansed, and the amount of moisture in the air after it leaves the cleansing apparatus for distribution in the system to w rich it is supplied.

Referring to the accompanying drawings:

Figure 1 is a front view of an air-washing ap'- paratus constructed in accordance with my invention, this view showing the screened end of the apparatus through which the air is drawn into the latter. Ifig. 2 is asection taken at the line 2 on Fig. 1 and viewed in the direction of the arrow. Fig. 3 is a seotion takcn-at the line 3 on Fig. 1, and viewed in the direction of the arrow. Fig. '4 is an enlarged view in sectional elevation of the upper end of the screen-and-baflle-construction illustrated in Fig. 3. Fig. 5 is an enlar ed view in sectional elevation of a detail; an Fig. 6 is a section taken at the line 6 on loig. 1 and viewed in the direction of the,

arrow.

The casing for housing the parts of the apparatus is represented at 7 and has its opposite ends 8 and 9 open for the passage of air through it. Its inner end 8 is restricted as illustrated and is adapted to be connected with a conduit containing a suction-fan (not shown) as is commonl provided in structures of this kind for rawing the air to be cleansed throuvh the apparatus.

A frame-wor referably composed of parallel vertical an e-irons 1() spaced a art, as represented in Fig. 2, are riveted to t e inner hooks over the a surfaces of the casing 7. Fixed to this frame-work at its upper end to extend completely across the interior ofthe casing 7 and inclined forwardly and downwardly is a shelf 11 joined at its lower forward dependingl flange 12 to the rear flanges 13 of a vertica series of parallel angle-irons 14 which form a.

frame between the irons 10 and the outer airinlet end 9 of the easing. The lower edge of the depending flange 1-2 of theV shelf 11 1s rearwardly and upwardly turned to 'afford an upwardly extending flange 15, for a purpose hereinafterex lained. y

Below'the s elf 1-1 is Aa vertical series of shelves 16 extending entirely across the interior of the casing, each vertically spaced apart from the-other as re resented,n and inclinjng downwardly vand. orwardly from their rear upper edge-portions, at which they are riveted to 'theirons V10, to the irons 14 to whichV they are fastened by dependin lflanges 17 thereon. The flanges l17fare forme with .rear upwardly vexten ing 'flanges 18, as described of the shelf 11, for a purpose hereinafter setv forth. The shelves 16 are preferably so inclined as to cause their'upper inclined portions to extend in a horizontal plane abovethat occupied by the opposed anges 18 as represented, for the purpose hereinafter explained.

Extending across the interior of the casing, at the upper extremities of the shelves 16, are baffles 19, eachof which is preferabl formed with a depending flange 2 0 at which it is riveted to the irons 10, a central section 21 extending at right-angles to the shelves 16 and a lip 22 at right-angles to the section 21, each baffle, by reason of the inclination of the-shelves, as described, extending in a plane above that occupied by the lower edgeportions of the shelf unmediately above it.

In each of the openings23 afforded by the intersection of the outer edge-portions of the shelves 16 and the vertical irons 14,v a screen 24 is removably suspended. Each of these screens fits flatwise against the adjal cent rear flanges 13 of the irons 14, and the ends of the upper edgeortion are c'ut away as indicated at 25, and ent `rearwardly and upwardly to form a hooleedge 26 which extends rearwardl beyond the irons 14 and cljacent flange 18, as most clearly illustrated in Fig. 5, the heights of the screens being such. as to cause each of them to reach short of the plane in which the shelf 16 immediately below it terminates,

i 3Q throug 'in Figs. bottom of each screen and the shelf immei and thus a series of spaces 27, as illustrated 3 4 and E, is afforded between the diately. below it. The washing water isi? supplied through 'a pipe 28 which terminates in a 4ipe 29 located above the upper shelf provided with a slot rom which itpours over the lower end of this shelf, passing over the screens 24 in the form of a continuous curtain. The air to be washed, entering the casing at the end 9,

under the action of the usual suction-fanl placed beyond the vrestricted end 8 of the casing'7, is drawn through the Water-curtain and screen 24, and thev air, and the water taken up by theV air, is caused to impinge against the shelves 16 and bafiies 19,' the water being thus 4recipated on the baflies and shelves from w lich it pours down inthe course as indicated by the dotted arrows in 4, falling from these sh lves at the open- .mgs 27. -The spent waterv uns into a tank 31 from which it maybe drained in any suitable manner to separate itI from the dirt washed from the air. It will be noted that the Witter in flowingV down the screens is caused in art'to be carried through each screen an that the Water carried through' the screens and recipitated onto the shelves .l6 is cause to run. off therefrom and in falling over the respective'screens below again is subjected to the suction action and again drawn through the screens to again be preci itated and flow to the next screens below, t iis action continuing until the water reaches the tank. It will be understood that the amount of water drawn through the screens depends on the strength of the suction-action produced. tage afforded by this construction is that of causing a water-curtain of the desired density to be rovided at all of the screens independent of) their position relative to the Water-supply ipe. As a means for removing clogging dlrt from the slot 30 in the pipe 29, -I' provide a sliding sleeve 32 which carries an upwardly-extending ton e 33 pro- 'ecting through'the slot 30, asil ustrated in ig. 6, this sleeve being secured to cables 34 and 35 which pass over vpulle the sleeve normally at one end of the 1 e 29 and the cable 35 liaving a handle by whigh the sleeve may be drawn lengthwise of the pipe to cause its Vtongueto move through the slot 30 and remove therefrom any clogging dirt.

portions of it are,

A decided advan- 's 36, thecable 34 carrying a Weight 37 u lich holds in the direction indicated by arrowsin-.IF 3

e for each screen-section is re-v .l

minimum the amount of moisture produced by evaporation of the .usually heated water on the baiiies.

The feature of supporting the screenisections in a manner -to permit of their removalk ,and replacing, enables the sections to be readily removed independentl of each other ,for purposes of repair, or the `ke.

It is'nzanifest that Where conditions vrequire it, as for instance where the air to be cleansed is especially dirtyfthe casing 'may be lengthened over that shown in the drawings, and any number of sets of shelves and baflieswith a that described, may be used.
